Instead of just passing a scale when getting a cached icon, pass both a
'paint_scale', the scale of which the icon will be painted on the
stage, and a 'resource_scale', the scale of the resource used for
painting.
In effect, the texture size will use the scale 'paint_scale * resource_scale'
in a ceiled value while the size of the actor will use 'paint_scale' when
determining the size.
this would load a bigger texture, but the downscaling would keep the visual
quality.

Create the surfaces for background shadows at scaled sizes and then draw on them
using logical coordinates, by setting the surface device scale accordingly.
Use the said surface scale when generating the actual shadow cairo pattern
but in such case, to reduce the number of code changes, is better to work in
absolute coordinates, and to do so:
1) Create a temporary shadow-spec copy with scaled values to absolute sizes
2) Invert the scaling on the shadow matrix
3) Do the actual painting in absolute coordinates
4) Set the shadow matrix scaling back to the logical coordinates.
Finally scale down the created shadow pattern surface size when painting it,
applying again a reverse scale to the matrix.

Pass resource-scale to drawing phase, and use it to create texture
surfaces scaled with the widget current scaling.
Also redraw by default widgets when the resource scale changes.

A fractional resource scale would mean we never use the fast path for
creating the shadow, because we'd cast the int to a float before
comparing, which would never match.
Instead compare the expected texture size with the source texture, to
actually potentially trigger the fast path.

The fade shader will draw the fade effect up until the border pixel. If
we set the bottom right coordinate to the outer edge of the pixel we
might end up not drawing the fade effect on all of the pixels. This
could for example happen if one logical pixel (clutter stage pixel)
consists of more than one physical pixel.

This commit makes StWidget manage the scale of which its associated
resources should be multiplied with. The resource scale is calculated
by clutter, and is retrieved by clutter_actor_get_resource_scale(). Due
to the resource scale not always being available, the getter may fail,
and the actual widget that draws the content will have to deal with
this situation.
As the resource scale depends on where on the stage the widget is drawn,
the resource scale will in general be available once the widget is
mapped.

instead of explicit screen arguments and `gdk_screen_get_number()`, as nowadays there
is always only one screen. This silences some deprecation warnings and removes
deprecated API.
Bonus: some code style cleanups

Since commit deec0bf2550, the texture cache is based on ClutterImage
rather than ClutterTexture. As ClutterImage (like all ClutterContent)
is only concerned with painting, it doesn't influence the size of the
actor it is added to at all, and the returned actor will now stay at
size 0x0 after the image has been loaded.
Set up the actor to follow the content's size instead, to get closer
to the previous behavior.

As the app menu is being phased out, it is no longer a good indicator
for GtkApplications. Instead, base the check directly on the appropriate
D-Bus properties.

too. All callers have been updated to use it.
This is a purely accessory change in terms of X11 Display usage cleanup,
but helps see better what is left.

It apparently uses no ClutterTexture specifics, and instead
only tries to match what StTextureCache used to return.
Since StTextureCache now returns ClutterActor, also use a
ClutterActor on ShellApp.

_st_create_shadow_pipeline_from_actor creates shadow pipelines
from actors. This function special-cases ClutterTexture as a
small performance improvement, since we can have access to the
CoglTexture easily with it. However, recent commits removed all
usage of ClutterTexture from GNOME Shell, rendering this optimization
useless. Instead, actors now may have a ClutterImage set as
their content, that can be used instead.
Replace the check for ClutterTexture with a check for ClutterImage,
and use the texture of the image when it is available.

The Magnifier class uses a small subtree of actors to track the
current cursor's position and sprite. Specifically, it uses the
deprecated ClutterTexture to paint the cursor sprites.
Add a new, very simple ClutterContent implementation to track the
cursor sprite, and replace the ClutterTexture by a ClutterActor.

This drops usage of Gtk/X11, replacing it with code that is dependent
of the Clutter backend in use. Another positive side effect is that
the keymap state will now be correct on wayland, since there were no
guarantees that X11 key state would reflect the current reality.

This is an expensive operation that is best avoided in the main loop. Given
the call doesn't care much about returning error or status, it can just
be made async within.
Every operation on a given file will be destructive wrt previous
operations on the same file, so we just cancel any pending operation on
it before batching the current one.

The last patch in the series, this one adapts StShadowHelper
to received a CoglFramebuffer. This is where we first touch
JavaScript with Cogl types, and as such, it depends on the
latest Mutter. Earlier versions of Mutter didn't have its
Mutter-Clutter GIR to generate types for various Cogl types.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/283
Same case of the previous patch; _st_paint_shadow_with_opacity()
uses cogl_get_draw_framebuffer(), and this patch makes it receive
a CoglFramebuffer as a parameter instead.
The cautious reader might notice that this commit apparently goes
against the long-term goal, for it introduces more instances of
cogl_get_draw_framebuffer(). This is not wrong, but these introduced
ones will be removed later on, when ClutterActor.paint() receives
a CoglFramebuffer as a parameter instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/283
This is in preparation for a future where only explicit frambuffer
APIs are available, i.e., cogl_get_draw_framebuffer() does not
exist.
There is absolutely no functional changes in this patch (nor the
following ones in this series), only rearrangements so that various
functions receive a CoglFramebuffer instead of using the draw
framebuffer.

This was called here just to end up emitting ::installed-changed,
which would trigger other g_app_info_get_all() calls. Cache it here
so it may be reused later on.
Handling those events is neccessary if a touch event that pressed down a
button turns out to be a gesture. In this case the button should be
released without emitting the clicked signal.
After loading the GdkPixbuf, StTextureCache unconditionally
creates a ClutterImage and, if it's not in the cache, add
it to the cache. That's a waste of resources when the image
is already committed to the texture cache.
Fix that by reusing the ClutterImage of the cache if it is
already there; otherwise, create a new ClutterImage as we
were previously doing.
ClutterTexture is a deprecated class that is simultaneously
an actor, and the content of the actor. Clutter's new model
is to separate painting (via ClutterContent) from actors.
Currently, StTextureCache relies on ClutterTexture to store
the loaded textures. This not only does not match the latest
practices of Clutter, but also generates various compile-time
warnings.
Port StTextureCache to store ClutterImages instead of storing
ClutterTextures. ClutterImage exposes the internal CoglTexture,
so no helpers are needed to match the current StTextureCache
API. Aspect ratio was dropped, but from my testing, it doesn't
change anything.
All callers have been updated to use MetaSoundPlayer. This drops direct
usage of libcanberra-gtk, and the X11 connection indirectly. One thing
worth noting is that we pass less metadata (eg. event x/y that might be
used for surrounding effects). This was all largely unused, so the
MetaSoundPlayer was made simpler.
